Distillation towers at a chemical factory
{"Image ImageDescription": "^BChemical factory.^b Distillation towers at a chemical factory. Distillation is the process of using heat to separate the different components within a mixture. The heat causes the more volatile components to vaporise more quickly than other components. These vapours can be collected and condensed by cooling, resulting in a solution which has a higher proportion of volatile chemicals than the original one.", "Image XResolution": "72", "Image YResolution": "72", "Image ResolutionUnit": "Pixels/Inch", "Image YCbCrPositioning": "Centered", "Image Copyright": "Science Photo Library"}
